Summary: The metacommunity organisation of aquatic insects in temporary ponds in southern Brazil is influenced by environmental factors (habitat structure; water chemistry; climate) and spatial factors, with differences observed between strong-flying and weak-flying insect subsets. Climate and fine-scale spatial factors play a significant role in structuring the composition of strong-flying insects, while weak-flying insects are more affected by local water chemistry and spatially structured climate.

Summary: Water-filled tree holes are unique ecosystems that have been extensively studied, with a focus on selected insect species, particularly mosquitoes. The size and resources of tree holes have a positive effect on species abundance and richness, but this effect is modulated by environmental variables. Other factors such as tree hole height, density, predation, and detritus type may also influence organism abundance and richness, but have been less studied. Future research should investigate the structure, functions, and dynamics of tree-hole food webs, as well as their interactions with terrestrial predators. Global studies on tree holes could provide valuable information on community structure and environmental drivers. Understanding these aquatic habitats in terrestrial ecosystems can serve as models for ecological research and indicators of environmental change.

Summary: Wetlands in China have a high rate of carbon sequestration, but there is still a lack of understanding about the emissions of greenhouse gases (GHGs) from these ecosystems. In this study, 166 publications were synthesized to analyze the variability and drivers of GHGs emissions from wetlands in eight subdivisions of China. The results showed that CO2 emissions contributed the most to the global warming potential (GWP) of China's wetlands, and certain wetland subregions had a significant impact on the overall GWP. Correlation analysis revealed the influence of factors such as temperature, elevation, rainfall, water level, soil pH, and redox potential on CO2 and CH4 emissions. This research provides valuable insights for global GHGs inventories and understanding the response of wetland ecosystems to environmental and climate change.

Summary: The study found that Late Triassic tetrapods show highest diversity at mid-latitudes, while the richness of pseudosuchians is highest at the paleoequator, and this pattern is retained throughout their subsequent evolutionary history. Pseudosuchians generally occupied a more restricted range of palaeoclimatic conditions, similar to modern reptilian ectotherms, while avemetatarsalians exhibit wider ranges, similar to modern endotherms, such as birds and mammals, suggesting important implications for the evolution of thermal physiology in dinosaurs.

Summary: This study investigated the relationship between earthworm communities and environmental conditions along an elevational gradient and around the treeline in the French Alps using sampling and structural equation modelling. The results showed that the ecotone associated with the treeline was the primary driving factor of earthworm communities, with soil and climate having only indirect effects. The species richness of earthworms did not decrease monotonically along the elevational gradient, potentially due to the dominance of taxa with high environmental tolerance and dispersal capacities. At 1800-2000 m elevation, earthworm communities were more abundant and diverse, with greater variability in body mass, which was largely explained by the structure and composition of the vegetation.

Summary: This study investigated the differences in waterbird-mediated endozoochory among five South American waterfowl species and the impact of seasonality on dispersal functions. The results revealed that these waterfowl dispersed 2,066 intact diaspores from 40 different plant taxa, with at least one diaspore present in 65% of fecal samples, predominantly from native amphibious and emergent plants. Seasonal variation was evident, with more diaspores found in the cold period compared to the warm period, and a strong interaction between bird species and season was the most important predictor of variation in both taxonomic richness and abundance of diaspores.

Summary: In subtropical seasonal ponds, the alpha diversity of zooplankton hatchling communities is primarily related to substrate heterogeneity, and the beta diversity of the total community is influenced by annual rainfall and substrate heterogeneity. The beta diversity of Cladocera is solely affected by annual rainfall, while substrate heterogeneity influences the overall beta diversity of Rotifera. Overall, the distinct relationships of the zooplankton groups with the explanatory datasets suggest differing sensitivities to impacts in habitat structure and climatic conditions in subtropical seasonal ponds.

Summary: Expansion of farming has negative impacts on freshwater biodiversity, with effects varying across taxa and regions. Research on the effects of agricultural expansion in the Neotropics, particularly in South American grasslands, is limited. The study found that landscape modification due to increased agricultural land use was associated with taxonomic homogenization in odonate communities in waterbodies within the Brazilian Pampa region, highlighting the importance of maintaining mixed-grassland and cropland land uses to limit negative effects on Odonata communities.

Summary: The termination of dormancy in aquatic invertebrates depends on multiple environmental cues, and the response to flooding can vary among taxa. In this study, the authors tested how multiple hydration events affect hatching dynamics and assemblage structure of invertebrate fauna. The results showed that the hatchling composition, but not richness, differed among hydration events and also varied within each hydration event. These findings have important implications for biodiversity assessment and the management of temporary ponds.

Summary: Bet-hedging is an ecological risk-aversion strategy that spreads the risk of reproduction to multiple events or conditions. This strategy is commonly observed in aquatic invertebrates in dry wetlands, where a subset of propagules hatch in the first flood and the rest hatch in subsequent floods. Harsh environmental conditions increase the reliance on bet-hedging. However, community-level assessments are needed to provide more robust support for the range of hatching strategies that exist in nature.

Summary: Climate change projections predict that warm temperatures and increased frequency of heat waves will strongly impact the embryonic development of aquatic species. A study on two Neotropical annual fish species found that temperatures above 27 degrees C were critical for embryo survival, while exposure to heat waves had similar effects on both species. The high-altitude species was more sensitive to increasing temperatures, indicating a higher threat to their population persistence under warming scenarios.

Summary: Wetlands are under threat worldwide due to climate change and land-use conversion. The existence of habitat complexes with different hydroperiods is crucial for the regional biodiversity of temporary wetlands. Loss of short-hydroperiod wetlands has the most significant impact on invertebrate beta diversity, but loss of long-hydroperiod wetlands is also important. Both hydroperiod extremes should be considered in assessing potential biodiversity declines associated with wetland loss.
